On August 1, 1966, after stabbing his mother and his wife to death the night before, Charles Whitman, a former Marine, took rifles and other weapons to the observation deck atop the Main Building tower at the University of Texas at Austin, then opened fire indiscriminately on persons on the surrounding campus and streets. Over the next 90 minutes he shot and killed 16 people (including one unborn child) and injured 31 others; while a final victim died in 2001 from the lingering effects of his wounds. The incident ended when a policeman and a civilian reached Whitman and shot him dead. The attack is one of the deadliest mass shootings in U.S. history.

I was 7 years old at the time, and don't have any memories of it. Probably didn't become aware of it until I saw something about it on "60 Minutes" fifteen years later.

That is the difference between now and the past. Big events took place in other parts of the country and didn't affect people nearly as much back then. Now, any event that happens, it spreads like a wildfire on social media and people feel like it happened right down the street.
